QSN-8843-1: FreeIPMI vulnerabilities

September 29, 2026

Summary

Several security issues were fixed in FreeIPMI.

Details

It was discovered that FreeIPMI incorrectly handled certain malformed Fujitsu SEL long-text responses, leading to a stack-based buffer overflow. An attacker in control of a malicious IPMI device could possibly use this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-85504)

It was discovered that FreeIPMI incorrectly handled short responses when retrieving Fujitsu SEL entries, leading to a stack-based buffer over-read. An attacker in control of a malicious IPMI device could possibly use this issue to cause FreeIPMI to crash, resulting in a denial of service. (CVE-2026-85505)

It was discovered that FreeIPMI incorrectly handled certain Dell iDRAC and CMC IPv6 system information responses, leading to a stack-based buffer overflow. An attacker in control of a malicious IPMI device could possibly use this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-85506, CVE-2026-85508)

It was discovered that FreeIPMI incorrectly handled certain Dell CMC system information responses, leading to a stack-based buffer overflow. An attacker in control of a malicious IPMI device could possibly use this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-85507)

It was discovered that FreeIPMI incorrectly handled FRU data responses that were larger than requested, leading to a stack-based buffer overflow. An attacker in control of a malicious IPMI device could possibly use this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-85509)

Internally-facing: only accessible when logged into the QuantaStor console/ssh as the qadmin administrative sudo user; generally lower priority. Externally-facing: part of a service the storage platform presents on the network (or the kernel), so potentially reachable over the network.
